Keep long-reach Ethernet links clean, predictable, and cost-controlled with this Cisco SFP-10G-LR compatible SFP+ transceiver. Designed for 10 GbE deployments over single-mode fiber, it supports LC duplex connectivity and 1310 nm optics for up to 10 km of reach in the right fiber plant. This module is a practical fit for switch uplinks, router interconnects, and server aggregation where multimode distance limits would force extra hardware or redesign. By matching the SFP+ form factor and 10 Gbps signaling expected in enterprise environments, it helps preserve port density while extending the network farther across buildings or between distribution points. For teams standardizing on compatible optics, this module offers a straightforward way to expand capacity without paying OEM pricing for every link. It is best suited for environments that need dependable long-distance transport, consistent interoperability, and a clean path to scale fiber infrastructure without changing the architecture.
